Turning is a slow process on
heavy ploughs and may not be
completed.
Incorrect oil flow
Try out whether various oil flow
rates affect the turning by adjust

ing the motor speed or flow rate
on the tractor valve. Turning
valves operate best at 25-35 l/
min. A high flow rate can return
pressure and lead to a reduced
turning performance
